Abstract
The utility model relates to a stand joist, particularly a double-piston elastic block-proof stand joist. The utility model is characterized in that a block-proof device consisting of cylindric piston springs and concave pistons is arranged in the cylinder of the stand joist. The utility model solves the problem that dust easily falls into the cylinder of the stand joist and blocks the cylinder of the stand joist.
Description
Technical field:
The utility model relates to a kind of grid that land, the anti-blocking grid that land of particularly a kind of double-piston elasticity.
Background technology:
The shop front of the gate of grange and window and both sides, street generally all is to adopt that to land grid and latch corollary apparatus antitheft.But since land grid opening upwards, it is stifled full that silt dust is easy to, and causes latch to be inserted not go down and come into force.
Summary of the invention:
The purpose of this utility model is to provide a kind of silt dust that prevents not fall into the grid that land that land in the grid.
The technical solution of the utility model is: the anti-blocking grid that land of a kind of double-piston elasticity, it is characterized in that: be provided with the anti-block apparatus that the female piston that made progress by top cylindrical piston and bottom opening and spring are formed by connecting in the grid cylinder landing, the female piston of its bottom contacts bottom the grid cylinder with landing, and the last plane of its top cylindrical piston is with to land grid cylinder internal orifice limit equal.
The utility model since the top cylindrical piston of anti-block apparatus with to land grid cylinder internal orifice limit equal, dust and earth can fall to landing in the grid cylinder, even having a small amount of dust in use repeatedly enters in the grid tube, also can fall in the female piston that bottom opening makes progress, can in time take out removing, very convenient.
Description of drawings:
Fig. 1 is the utility model schematic diagram.
Among the figure: 1, land the grid cylinder; 2, female piston; 3, spring; 4, cylindrical piston.
The specific embodiment:
The utility model is formed by landing grid cylinder 1, female piston 2, spring 3, cylindrical piston 4.Female piston 2 and cylindrical piston 4 connect into an integral body by spring 3, the bottom of female piston 2 with land grid cylinder bottom connection and touch, the last plane of cylindrical piston with land grid cylinder internal orifice limit and parallel.
